Great resource for old phonograph cylinders

Belfer Cylinders Digital ConnectionThe Belfer Cylinders Digital Connection provides online access to digital audio files of cylinders in the Belfer Audio Laboratory and Archive. Belfer�s cylinder collection includes over 22,000 cylinders, 12,000 of which are unique titles. The goal of this digitization project is to provide 6,000 audio files by 2010.

The digital recordings, provided in both MP3 and WAV file format, can be searched or browsed by genre/subject.

6,000 files is 30/day for a 200 day work year. They are going to be busy!
Sounds like a great resource for samplers although they are claiming ownership of the scan and stipulate non-commercial or scholarly use only.
